What do I do?
* If you were posting a comment or making a post on your blog then do not press BACK on your browser. Wait 5 minutes and press the refresh icon on your browser. Your comment or post will be sent as normal.
* If you are browsing a blog here just wait a few moments and hit refresh. The page you were expecting will appear.
I have wait at least half hour and the maintenance continues. How much time gonna take this situation?
